Metallic yarn is a kind of yarn made of gold and silver, or a thin strip of chemical fiber film with gold and silver luster. Traditional metallic yarn is divided into flat gold wire and round gold wire. The gold foil is glued on the paper and cut into 0.5mm thin strips to form flat gold thread. Then the flat gold thread is wrapped outside the cotton yarn or silk thread to form round gold thread. Now some valuable traditional fabrics such as Yunjin still use the traditional metallic yarn silk. The chemical fiber film metallic yarn developed in the 1940s is made of two layers of butyl acetate cellulose film sandwiched with a layer of aluminum foil and then cut into thin strips. Later, polyester metallic yarn were made of polyester film by crossing aluminum and adding color coating.
